%
% This package implements commands for the creation of PDF Objects,
% Form XObjects, Image XObjects, annotations, links, marked content (BDC/EMC)
% and for manipulating the PDF catalog.
%
% Supported workflows:
%
% pdflatex, lualatex
% latex-->dvips-->ps2pdf or Distiller
% latex-->dvipdfmx
% xelatex
%
% Package options:
%
% xetex
% dvipdfmx
% dvisvgm (basic support: \pbs_literal:nn, \pbs_pdfannot:nnnn,
% \pbs_pdfxform:nnnnn\pbs_pdfrefxform:n)
% bigfiles (for embedding large files as stream objects; only relevant for
% dvips mode, ignored otherwise)
%
% Commands defined:
%
% \pbs_pdfobj:nnn
% #1: predefined PDF object ID to be used for the current obj; may be empty
% #2: type of object ( generic | dict | array | stream | fstream )
% #3: if #2==
% `generic', then single basic object, such as 3.141, (foo), true, /Name
% `dict', then PDF key-value dictionary
% `stream', then
% {stream attributes as PDF key-value dictionary}{content string}
% `fstream', then
% {stream attributes as PDF key-value dictionary}{file name}
%
% if #3 && #1 are both empty, an object reference will be reserved for later
% use as #1
%
% \pbs_pdflastobj:
% inserts object ID of PDF object created/processed during most recent call
% of \pbs_pdfobj:nnn
%
% --------
%
% \pbs_pdfannot:nnnn
% #1: width, #2: height, #3: depth, #4: dictionary (key-value)
%
% \pbs_pdflastann:
% inserts object ID of PDF object created during most recent call of
% \pbs_pdfannot:nnnn
%
% --------
%
% \pbs_appendtofields:n
% #1 object ID of PDF annotation; annotations of /Subtype/Widget
% should be appended to the /Fields array of the global /AcroForm dictionary
%
% --------
%
% \pbs_pdflink:nn
% #1: dictionary (key-value), #2: text
%
% --------
%
% \pbs_pdfdest:nnnn
% #1: name, #2: fit | fitb | fitbh | fith | fitbv | fitv | xyz | fitr
% #3: zoom, #4: text
%
% --------
%
% \pbs_pdfxform:nnnnn
% #1: add pgf/tikz resources (transparency, shading)? (0|1) %dvipdfmx/xetex
% #2: write immediately to PDF? (0|1); eg 1 for appearances; pdftex/luatex
% #3: additional resources %all BUT dvips
% #4: additional dictionary entries
% #5: savebox number
% creates PDF Form XObject from savebox content
%
% \pbs_pdflastxform:
% inserts object ID of PDF Form XObject created during most recent call of
% \pbs_pdfxform:nnnnn
%
% \pbs_pdfrefxform:n
% #1: xform object ID
% inserts the PDF Form XObject into the current content stream, that is,
% typsets the PDF Form XObject
%
% --------
%
% \pbs_pdfximage:n
% #1: bitmap image file name
% creates PDF Image XObject from /bitmap/ file for use as bitmap resource
% in 3D context
%
% \pbs_pdflastximage:
% inserts object ID of PDF Image XObject created during most recent call of
% \pbs_pdfximage:n
%
% --------
%
% \pbs_literal:nn
% #1: keyword (empty) | direct | page
% #2: raw PDF/Postscript code
% implements \pdfliteral{...}, \pdfliteral direct {...},
% \pdfliteral page {...} from pdfTeX, and
% \special{" ...} and \special{ps: ...} from dvips
%
% --------
%
% \pbs_pdfcatalog:n
% #1: dictionary (key-value)
%
% --------
%
% marked content BDC/EMC operators
% \pbs_pdfbdc:nn ...
% ... \pbs_pdfemc:
% #1: tag, #2: properties dictionary obj ID
%
% --------
%
% \pbs_add_form_font: (pdfLaTeX, LuaLaTeX)
% adds current font as a resource to the global /AcroForm dict, allowing
% the font to be used in PDF Forms (theoretically, see
% https://acrobat.uservoice.com/forums/590923-acrobat-for-windows-and-mac/
% suggestions/33077827-bug-in-text-field-forms-embedded-opentype-font )
%
% \pbs_last_form_font: (pdfLaTeX, LuaLaTeX)
% expands to current font's resource name; to be used in the /DA (...)
% entry of the Form dictionary

% This package implements commands for the creation of PDF Objects,
% Form XObjects, Image XObjects, annotations, links, marked content (BDC/EMC)
%
% Supported workflows:
%
% pdflatex, lualatex
% latex-->dvips-->ps2pdf or Distiller
% latex-->dvipdfmx
% xelatex
%
% Package options:
%
% xetex
% dvipdfmx
% dvisvgm (basic support: \pbs_literal:nn, \pbs_pdfannot:nnnn,
% \pbs_pdfxform:nnnnn\pbs_pdfrefxform:n)
% bigfiles (for embedding large files as stream objects; only relevant for
% dvips mode, ignored otherwise)
%
% Commands defined:
%
% \pbs_pdfobj:nnn
% #1: predefined PDF object ID to be used for the current obj; may be empty
% #2: type of object ( generic | dict | array | stream | fstream )
% #3: if #2==
% `generic', then single basic object, such as 3.141, (foo), true, /Name
% `dict', then PDF key-value dictionary
% `stream', then
% {stream attributes as PDF key-value dictionary}{content string}
% `fstream', then
% {stream attributes as PDF key-value dictionary}{file name}
%
% if #3 && #1 are both empty, an object reference will be reserved for
% later use as #1
%
% \pbs_pdflastobj:
% inserts object ID of PDF object created/processed during most recent call
% of \pbs_pdfobj:nnn
%
% --------
%
% \pbs_pdfannot:nnnn
% #1: width, #2: height, #3: depth, #4: dictionary (key-value)
%
% \pbs_pdflastann:
% inserts object ID of PDF object created during most recent call of
% \pbs_pdfannot:nnnn
%
% --------
%
% \pbs_appendtofields:n
% #1 object ID of PDF annotation; annotations of /Subtype/Widget
% should be appended to the /Fields array of the global /AcroForm dictionary
%
% --------
%
% \pbs_pdflink:nn
% #1: dictionary (key-value), #2: text
%
% --------

% #3: zoom, #4: text
%
% --------
%
% \pbs_pdfxform:nnnnn
% #1: add pgf/tikz resources (transparency, shading)? (0|1); dvipdfmx/xetex
% #2: write immediately to PDF? (0|1); eg 1 for appearances; pdftex/luatex
% #3: additional resources; all BUT dvips
% #4: additional dictionary entries
% #5: savebox number
% creates PDF Form XObject from savebox content
%
% \pbs_pdflastxform:
% inserts object ID of PDF Form XObject created during most recent call of
% \pbs_pdfxform:nnnnn
%
% \pbs_pdfrefxform:n
% #1: xform object ID
% inserts the PDF Form XObject into the current content stream, that is,
% typsets the PDF Form XObject
%
% --------
%
% \pbs_pdfximage:n
% #1: bitmap image file name
% creates PDF Image XObject from /bitmap/ file for use as bitmap resource
% in 3D context
%
% \pbs_pdflastximage:
% inserts object ID of PDF Image XObject created during most recent call of
% \pbs_pdfximage:n
%
% --------
%
% \pbs_literal:nn
% #1: keyword (empty) | direct | page
% #2: raw PDF/Postscript code
% implements \pdfliteral{...}, \pdfliteral direct {...},
